How different the same hall feels with another orchestra onstage. For starters, at Monday’s Taiwan Philharmonic concert, women not only outnumbered men — they were extraordinarily well-represented even in the sections (double bass, brass, and especially, leadership positions) that remain male-dominated in this country’s orchestras. There was no concertmaster entrance; in fact, the orchestra entered the Davies stage en masse. And the applause, after every movement, didn’t feel wrong.
